The hospitality and cooperation of the staff of Colorado National Monument added significantly to the pleasure of mapping the Monument and surrounding area, especially by providing housing with showers, kitchen, and a terrific view. In particular, the friendly support of the Superintendent Steve Hickman and his staff of park rangers made normally difficult tasks much easier. Pat Perrotti, Resource Manager for the Monument, went out of his way to fill us in on current geologic events at the Monument. Bill Rodgers, Protection Ranger, spent a day in the field with us to locate critical boundaries in the new southern addition to the Monument. Bruce Heise, National Park Service Geologic Resources Division liaison to the USGS, helped make the map a high-priority product. Joe Gregson, also with the Geologic Resources Division, obtained and transferred digital line graph (DLG) data critical for a legible topographic base for the map. The partnership with both the Colorado National Monument Association and the National Park Service has been instrumental in creation of this product for the public. In the USGS Earth Surface Processes Team, Paco Van Sistine provided prompt and critical GIS help. The constructive reviews by Bruce Bryant and Jim Yount of the USGS significantly improved the quality of the map and text. Discussions with Robert Young of Grand Junction were valuable and invigorating. The radiometric dating by Mick Kunk and Dan Unruh of the USGS provided critical constraints on the ages of Proterozoic events. The Carbon-14 dates supplied by Jack McGeehin of the USGS not only gave us the timing for geologic events during the late Quaternary, but also allowed us to date the minimum period of Native American habitation in the canyons of Colorado National Monument.
To update the interpretation and increase the scale of geologic mapping, provide a geologic map for the public to use at Colorado National Monument, and to provide sufficient geologic information for land-use and land-management decisions.
